Canada and Antisubmarine Warfare in the First World War
When the First World War began in August 1914, the Royal Canadian Navy (RCN) was unprepared to fight a war at sea. Founded only in 1910, it consisted of two obsolete cruisers, HMCS Niobe and HMCS Rainbow, and about 350 regular sailors, augmented by 250 reservists. During the war, it was assigned a growing number of tasks, which it was ill-equipped to perform. This included protecting Canadian coastal waters against German U-boats. The RCN scrambled to find ships and sailors but was ill-equipped to fight enemy submarines, which sank several vessels in Canadian waters in 1918.
